HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 738,320, dated September 8, 1903.

Application filed November 6, 1902. Serial No, 130,353. (No model.)

f9 all whom it 777/66Z/ concern.-

Be it known that we, JOHN JOSEPH GUN- THER and FRED. E. GEIGER, citizens of the United States of America,residing at Chicago, in the county of Cook, State of Illinois, have inventeda new and useful Improvement in Heating-Drums, of which the following is a description.

Our invention relates to an article of manufacture, an improved heating-drum, used to be attached to oil or gas burners, whereby the heating capacity can be regulated and the smoking of burners and the odor of obnoxious gases entirely avoided by the arrangement of certain new and simply constructed parts, as represented in the accompanying drawings, which, with the letters of reference thereon, form part of this specification.

In the drawings, Figure 1 represents in front view the heating-drum in connection with a burner. A portion of the lower end part of the drum is shown in section to exhibit the position of internal parts. Fig. 2 is a central vertical section of the foregoing one without the burner. Fig. 3 is a top view of Fig. 1, the lid of the same taken oif. Fig. 4 is a detail in perspective View, on enlarged scale, of one of the parts of the apparatus.

In describing our invention, an improved heating drum as an attachment to vaporburners, we refer to Fig. 2 in the accompanying drawings, in which the construction of the apparatus is fully illustrated, and the same consists of two cylindrical-formedindependent bodies of suitable metallic material, an outside and an inside one. The outside body is a cylinder with smooth surface and represents the drum A, open at top and bottom ends,

inside of which is secured in suspended position a cylindrical-formed vessel 13, which is of corresponding length with the said drum, but measuring proportionally less in diameter in comparison with the same, and its lower end is closed with a spherical-shaped bottom a, while the upper end of that vessel is open and connected there with a lid b in size to rest on the upper end of the drum and closing the opening of the same. The drum and the vessel bearing each near their upper end portion a limited number of equally-divided tongues c, c, and d, the same are of equal length and arranged in horizontal rows one below the other and at parallel distance in the manner that the lower row of the tongues 0 appear when viewed in top view situated in middle of the space between the tongues c of the upper rows, as shown in Fig. of the drawings. These tongues form an integral part of the material of the drum A and the vessel B and are produced by two parallel-made slits h and t into the upper end of the same and extend in downward direction as far as to the intended position of the tongues, which are formed simply by bending the cut portion between the said slits down in an elevated position and get them in overlapping contact by turning the vessel around its axial line for raising or lowering the same to a position in accordance to come in joining contact with the higher or lower arranged row of tongues and to secure the vessel in its suspended position. The tongues are shaped lengthwise in hollow rounded form, Fig. 4, to fit one in another to prevent thereby slipping from their resting-place.

The object of having the vessel resting in higher or lower suspended position is for the purpose to get the bottom portion of the same in close contact with the alterableness of the combustion of the fuel from any kind of suit able reservoir or burners L used to compel the heated air developed inside the apparatus'to escape through the openings f of the vessel or m of the drum caused by the cut portions to form the tongues d and c by the draft from the perforations g at the lower end of the drum.

To carry the apparatus to any desired place, the same is provided for that purpose with a swinging handle 0 of suitable design and is with its ends fastened to' the drum A in the usual manner.

Having thus described our invention, we claim- '1. A heating apparatus consisting of a pair of separably-connected cylindrical parts of pair of separably connected cylindrical formed parts of equal length,an outside larger part representing the drum, the same surmounting a smaller vessel, both of these parts provided at their upper ends with corresponding port-holes, the outside larger part or drum having draft holes or openings, the said apparatus provided with a lid fastened to the inner part or vessel and having a handle eon- 1o nected wit-h the outside part or drum, substantiaily as described for the purpose set forth.

In testimony whereof we have hereunto set our signatures in the presence of two subscribing witnesses.
